I revisited this cocktail and used 1 oz of Jamaican Overproof white rum. I think this was even better with little funk from the Jamaican pot stilled rum! As John Hinojos stated below it really does have a hint of Sarsparilla!
I searched for a cocktail with pineapple after cutting a fresh pineapple today. I had all the ingredients for this one and it sounded good to me, I did substitute Cointreau for the triple Sec, and then omitted the agave nectar, it was well balanced and tasted wonderful!
What a lovely cocktail, I made mine with Dolin Genepy, instead of Green Chartreuse, so hard to buy right now. Thanks for the history! I think Frank Fogarty is a distant relative and chuckled when I read about him in the history. My grandfather was born a few years before Frank, John J Fogarty also born in Tipperary.
